UNITED STATES PATENT OFFICE.

MORDICAI LEVI, OF CHARLESTON, IVEST VIRGINI PAVEMENT FOR STREETS OR ROADS.

SPECIFICATION forming part of Letters Patent No. 401,752, dated April 23, 1889.

Application filed November 19, 1888. Serial No. 291,284. (No model.)

To all whom it may concern.-

I-le it known that I, MORDICAI LEVI, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of 7West Virginia, have invented and produced a new and Improved Pavement for Streets or Roads; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part thereof.

My improved pavement is made in the following way: After the required grading or filling to receive the road-bed is complete, I .first put. down a layer of comminuted stone-u such as broken stone or slate, gravel, or sand.

`Upon this I place a layer composed of asphalt or its equivalent tar suitably prepared and mixed With any comminuted material capable of giving the layer bulk and consistencysuch as pulverized stone or slate, sand, gro und bark, sawdust, or Wood pulp. Upon this I place a layer of sand, and upon this I place a surface layer of hard-burned brick, stone, paving-blocks, Wood, or other suitable material.

Having reference to the drawing, a represents the earth properly graded. b is the layer of comminuted stone. c is the layer of asphalt mixed With a suitable comminnted material. d is the layer of sand, and e is the surface layer. A andyB represent the curbs. The pavement thus formed is cheap in construction and contains all the elements of durability.

That I claim as my invention, and desire to secure by Letters Patent, is-

'A pavement consisting of a first or bottom layer of comminuted stone, of a second layer composed of asphalt and any suitable-comminuted material, of a third layer of sand, and of a fourth or surface layer of any suitable material, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

MORDICAI LEVI.
